Errors connecting to solrcloud using CloudSolrClient

I'm trying to connect to solrCloud using solrj CloudSolrClient, but am getting errors.
Used to directly call a single solr node, now switching to solrcloud. I have tried various different url formats as specified from documentation online.
SolrClient solrClient = new CloudSolrClient.Builder(zkUrl).build();
SolrQuery solrQuery = new SolrQuery();
solrQuery.setRequestHandler(FIELD_LIST_HANDLER);
QueryRequest req = new QueryRequest(solrQuery);
req.setBasicAuthCredentials(zkUser, zkPassword);
QueryResponse response = req.process(solrClient, core);
When using the following zkHost strings I get the various errors.

What do I need to change to successfully query solr through zookeeper using solrj CloudSolrClient?
I have successfully communicated with the zookeeper instance from terminal.
$ echo stat | nc host 2181
Zookeeper version: 3.4.14-4c25d480e66aadd371de8bd2fd8da255ac140bcf, built on 03/06/2019 16:18 GMT

It turns out that both solrurls and zkurls can be provided to the CloudSolrClient.Builder. I was able to get past the previous issue by using the SolrClient solrClient = new CloudSolrClient.Builder(hosts, Optional.empty()).build();which accepts zkUrls whereas CloudSolrClient.Builder(hosts).build() accepts solr Urls

I also got this ClientProtocolException when the configuration itme clusterprops.json was not available in zookeeper /

Get full Java stack trace from IBM Bluemix using logstash 2.3.4

I am very new to IBM Bluemix and Logstash.
My application is based on Spring Boot + Log4j which was deployed into IBM BlueMix.
Goal:
Reading entire java stack trace + BlueMix log and write into a file in local Linux Server.
I don't want to use elastic search & Kibana. I think it is overkill for my requirement. I don't want fancy GUI thing, but a basic text file which contains all log information.
What I did till now:
Installed & Setup logstash.
Able to write bluemix log into a file in my local server.
Below is my Logstash conf file. As I want entire log, I am not using any filter. (based on my 1 day old logstash knowledge)
input {
tcp {
port => 5000
type => syslog
}
}
filter {
}
output {
file {
path => "/app/uot0/cloud/logstash/logstash-2.3.4/tmp/access_log"
}
}
Problem:
Logstash output file "access_log" is NOT containing full stack trace from a Java Exception, it contains only name of that exception.
(part of) Original log from BlueMix console:

How can I get the full stack trace for Java Exceptions, so that it will be useful for debugging?
Any help will be appreciated...

Web-service client on Websphere throws NullPointer on method calling

jaxws-spring
WebSphere 8.5.5.2
for our web-services interactions, and now we get stuck with such "cause" when we call any web-method on the client-side -

Web-service client initialisation comes out with no any errors -
URL service_endpoint;
service_endpoint = new URL(endpoint);
service = new UDHandlersServiceImpl(service_endpoint, SERVICE_QNAME).getUDHandlersServiceImplPort();
NullPointerException occurs after calling any method of "service". And it doesn't even reach server side - because it doesn't have any logs there. Furthermore - such situation occurs only on the WebSphere - we deployed our client application on the Tomcat (server remained on websphere) and it worked fine. One more thing - SoapUI does not have any problems interacting with server side too.
We tried to switch classLoadings to parentLast for client application - with no success.
Also I can't even find sources for "org.apache.axis2.jaxws.message.databinding.JAXBUtils.getJAXBContext(JAXBUtils.java:445)". I googled it and didn't find this version of JAXBUtils. But even if i did, i think, it wouldnt be useful...
I hope someone can help us with that unobvious problem.
Thanks beforehand.
===== updated======
When we remove jaxb libraries from endorsed dir (or appServer/classes) problem seems to disappear but in case of arising webExceptions(faults) server throws

and returns no answer to the client.

We've realized that our exceptions didn't contain 3 required methods -
//============required==================
public DocumentValidationException(String message, ErrorsBean errorsBean, Throwable cause) {
super(message, cause);
this.errorsBean = errorsBean;
}
public ErrorsBean getFaultInfo() {
return errorsBean;
}
public DocumentValidationException(String message, ErrorsBean errorsBean) {
super(message);
this.errorsBean = errorsBean;
}
//======================================
so, now it does.
And also we had some wrong target namespaces in it at the #WebFault annotations.
Here is the link with similar problem - https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777-0000-0000-0000-000014076927#77777777-0000-0000-0000-000014083314

Jsp to my sql connection error.

This error please help:
HTTP Status 500 -

you need to pass database connection url, instead of just localhost, like jdbc:mysql://localhost:3306/
here's a good example

Patrick,
AS per the Exception "SSL configuration properties are null. Could be a problem parsing the SSL client configuration." .
Please check the path of the CLIENTSSL variable (ssl.client.props) in the runbatch.sh file. Looks like the script is unable to find ssl.client.props file.
